ein -i,inportant-'objectof thepresent inventipn i -to provide a'seal"otherabovereferreditogt l e an', gingluinga loopecrstraI-i` having its :Gildsingsert'ed`inahousingorcasingtogether with`-interlocking means adapted for interlocking engagement upon an inserting movement of one end of the strap relative to the other end thereof and adapted to prevent withdrawal of the ends of the strap from the housing.

A further object of the invention is to provide interlocking means for the inserted ends of the strap of simple and practical construction and which, at the same time, effectively secure the ends of the strap against withdrawal and also in which the housing or casing may be manufactured at relatively low cost from a single blank sheet of material Ahaving its edges secured to each other by the insertion of the ends of the strap into the housing.

A still further object of the invention is to provide a, device of this character of simple and practical construction, which is eilicient and reliable in use, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a plan view showing the end of the strap prior to its insertion in the housing for locking engagement therein.

2 Claims. (Cl. 2922- 73117i1 Referring nowf-to th e-'drayving'findetai-l, -whereini for the printf-pose-V of illustrationa I have;disclosedJIA a preferredembodiment; of theinvention,v thef numeralfE designates -i'/h'es irap,` which -is' formed from a stripVY off* relatively thin;vr exible; metal;` andis formed; adjacent-one end withl'a longitudie nall-y extending s lcttwhiieits other endisffformedi with,v a at:u fork* or-head il toA providelapair MofJ spaced Vparallelringe-rs* rseparat'edbynneansor a longitudinally extending slot 9.

The material cut from the slot 9 forms a tongue I0 which is connected at its inner end at the inner end of the slot 9, the outer end of the tongue being bent under itself at an acute angle, as indicated at Il, and the tongue I0 is bent upwardly at an inclined angle above the ngers 8, as shown to advantage in Figures 2 and 5 of the drawing.

A housing or casing is designated generally at I2 for enclosing the head 1, the housing being stamped or cut from a single sheet of bendable lightweight metal, the housing being bent along a transverse medial line I3 upon itself to form top and bottom sections I 4 and /I5, the sections being pressed outwardly at their central portions to provide a chamber I6 therein.

The side edges of the sections I4 and I5 are formed with anges I1 and I8 disposed in superposed relation and secured to each other by a prick and press method through the use of a sharp tool in a manner well known in the art and as indicated at I9.

The sections I4 and I5 of the housing at the open end thereof form lips 20 and 2 I, respectively, which denne an opening 22 through which the ends of the strap are adapted for insertion into the chamber IB in the manner as illustrated in Figure 5 of the drawing.

In assembling the device, the head 'I is placed between the sections I 4 and I5 and the sections then secured to each other and the other end of the strap 5 is then inserted through the opening 22 until the tongue I0 engages in the slot 6. The ends of the strap will thus be secured against withdrawal in the housing I2. When the strap is drawn back slightly the lock is sealed, as shown in Figure 8.

The strap 5, adjacent the head 1, is formed with a frangible portion 23 of reduced width provided with an opening 24 so that when the seal is to be removed the strap can be easily broken and removed.

It is believed the details of construction, manner of operation and advantages of the device will be readily understood from the foregoing without further detailed explanation.

Various modications and changes are contemplated and may obviously be resorted to since only a preferred embodiment of the invention has herein been disclosed.

said last mentioned strap end having a slot for receiving the tongue upon insertion of said end in the casing, and said tongue being disposed with its secured end extending away from the entrance Having thus described the invention, what I 5 opening and its free end extending back toward claim is:

1. A seal comprising an elongated strap, a V-shaped tongue struck-out of one end of the strap having a longer ieg fixed to the strap and a shorter, free leg, said strap end having a longitudinally extending outwardly opening notch defined by the struck-out tongue and through which the free leg of the tongue normally extends, the other end of the strap having a, slot to receive the tongue when the ends of the strap are folded one upon the other; and a casing enclosing the ends of the strap, the free leg of the tongue being cammed through said slot for non-disengagably interlocking the strap ends when the said other end of the strap is moved in a direction outwardly of said casing, the apex of the tongue being disposed to initially move through the slot when the tongue is cammed therethrough.

2. A seal comprising an elongated strap having one end provided with a struck-up V-shaped tongue forming a longitudinal outwardly opening notch in said strap end, a casing in which said end is disposed, said casing having an entrance opening for receiving the other end of the strap,

the entrance opening and through said notch whereby said free end will pass entirely through said slot upon partial withdrawal of the last mentioned strap end to non-disengagably interlock the strap ends in the casing and to position the terminal portion of the last mentioned strap end between the legs of the V-shaped tongue.
